摘要
乐滩水电站经过十几年的运行之后,出现局部幕后排水孔渗流量异常的情况。笔者针对该问题,通过对原始资料、运行资料及现场相关试验结果的分析,找出渗流量异常的原因;分析异常情况对坝段稳定的影响;并提出合理的处理措施和技改建议。
After more than ten years of operation, the local seepage flow of the backstage drainage holes in Letan Hydropower Station is abnormal. In view of this problem, the authors find out the causes of abnormal seepage flow through the analysis of original data, operation data and field test results, analyse the influence of abnormal conditions on dam stability, and put forward reasonable treatment measures and technical improvement suggestions.
